Hello @Tallyb
Thanks for opening this issue. Will check it out later this week.

@Tallyb I had a similar issue with optional chaining in the template, but for me, the problem was that the template was not properly formatted, and the interpolation expression had bad formatting, i.e. having space before and after, like the following:

<span>{{
project?.title ? project.title : ""
}}</span>

If possible, can you please provide more info (more piece of code) about the problem you had?

I hope this issues doesn't happen with official migration angular/angular#57082
